(ANDREWS) - An anthropologist is studying skeletal remains found at the Salamonie Reservoir in Northern Indiana.

Park Manager Jim Duguid says the remains are believed to have come from an old cemetery that was moved in the 1960s before construction of the reservoir. The area is about 30 miles southwest of Fort Wayne.

Keith Keeney, a U.S. Army Corps of Engineers forensic anthropologist, says some of the 700 graves may have been overlooked or may not have been marked.

The remains are believed to come from five of the graves. They were found in early November by a fisherman who notified officials. The rising and falling of the reservoir apparently wore away the soil, exposing the graves.

Keeney believes the bodies were buried sometime in the late 19th or early 20th century. The bodies will be re-buried in the New Monument City Cemetery.
